Most Electrifying UFC or Pride moments...

My most electrifying moment was when randy returned to fight Tim, and the 1st punch he threw put Tim on his a$$. I jumped & scremaed, everybody at my house jumped and screamed, the whole UFC crowd errupted. Joe Rogan was freking out. That was an amazing moment.

For me, it would have to be when Scott Smith and Pete Sell were high-5ing and hugging each other in between each exchange in their fight.
I can't explain it, but there's something special about when 2 fighters show that level of sportsmanship to each other while they're beating each other up.

-I think when Anderson Silva kneed the f--- out of Franklin and changed the course of the MW division for almost a decade it was pretty cool
-Chuck's beating on Tito the first time.
-Forrest Griffin beating Shogun/Rampage
-Serra beating GSP
-Aldo running into the stands after KO'ing Mendes
-Liddell/Couture trilogy
-Tito calling out both Liddell/Shamrock
-BJ Penn return announcement at UFC 56
-Henderson/Crocop murder over Wanderlei
-Belfort KO'ing Silva in 12 seconds
-Tito shooting the two finger salute to the Lion's Den
-Pete Williams KO of Mark Coleman
-Kimo knocking Gracie out of UFC 3 with a broken hand and running out into the octagon to celebrate (after losing the fight )
-JUST BLEED guy

I also remember when Anderson came to the UFC and got a title fight for his second fight. A lot of naysayers thought this was ridiculous but I had a gut feeling things would change...

I feel like around this time, there was a shift of gears in the UFC. The Matt Hughes, Rich Franklin, Liddell era all shifted to "newer" fighters. That might not be the right word, I can't quite get it, but it was some new momentum.
